Provide adapter to manipulate DocumentModel as a blob
-----------------------------------------------------
Key: NXP-2982
URL: http://jira.nuxeo.org/browse/NXP-2982
Project: Nuxeo Enterprise Platform
Issue Type: User story
Reporter: Thierry Delprat
Assignee: Thierry Delprat
There are several place in the code where we need to manipulate the
DocumentModel as a blob :
- in all download links
- in the preview addon
- in all file oriented interfaces (WebDav, Flex filemanager ...)
- ...
Each time, there is ugly code that looks for file:content.
=> This needs to be encapsulated
Furthermore some services (like tranformers or Tiling) take as input something
that is homogene to a blob.
In these case, using a blob instread of a Adapter DocumentModel makes us loose
information : there is not way to compute a cache key based on the blob.
We need to define :
- a BlobHolder interface
(that can be implemented on top of DocumentModel or on top of other resources)
- a pluggable adapter factory to manage how BlobHolder is defined for each
DocumentModel Type
